I'm looking at using Shopify POS. I currently use Vend on a windows laptop as our cash register. We sell antiques and lots of other items that don't have a barcode. They often require a brief description with each item as well as a price list we use in excel. An actual laptop makes more sense for us then a tablet. Since there is no windows application for Shopify POS, can I use a chrome book instead of a tablet?
